5.3 Adjusting the Operating Pressure
and Flow Rate
• • • • •
You can adjust the operating pressure and
flow rate in two different ways:
1. With the pressure and volume control on
the pump head
– Screwing in the adjusting screw increases
the flow rate and operating pressure
– Screwing out the adjusting screw
decreases the flow rate and operating
pressure.
2. With the servo pressure valve on the hand
spray gun
– Turning the control sleeve to the right
increases the operating pressure and water
volume
– Turning the control sleeve to the left
decreases the operating pressure and
water volume.

5.6 Operating with steam
•
When operating temperatures are above
98°C, the operating pressure must not exceed
32 bar. Thus, the standard high-pressure
nozzle must be replaced by a steam nozzle
(available as an accessory).
• • • • •
Adjust the thermostat to the desired
temperature.
•
We recommend the following cleaning
temperatures:
100 – 110°C for depreservation, dirt containing
up to 140°C for thawing aggregates, partial
•
Rotate the pressure and volume control on
the pump head to the lowest value.

When you have finished operating the
appliance with steam, you should adjust the
